To aZZ whom it cmwomi Be it known that we, EDWARD il lsoM and JOHN E. BELL, citizens of the United States, residing, respectively, at il iuuetlia, county of (look, and State or llllinois, and

Brooklynycounty of liiiugs and State of New York, have invented certain new and useful Improvements in Condensers, of which the following is a spe fication.

Our invention is designed more particularly for use in condensing vapors from oil stills, lThOH l1 it will be apparent from the following oescriptiou taken with the drawings that it is or general application for condensing. vapors of liquids other than oil The usual practice otcoodeusing distiilates from oil stills is to pass them through tubes or other passages which are cooled by means pose of exemplilication only and that the thereof.

scope of the invention is defined in the fol" lowing claims "in which we have endeavored to distinguish it from the prior art so far aslmown to us without however relinquish iug or abandoning any portion. or feature In the drawings Fig. l is a plan viev; of our improved couoleusci". and Pi 2?, i a. ver tical central section thereof, parts being SllOWll in elevation. V

In (1318 preferred l'onn of the invention shown the main body ol' the condensate is contained in a tank 5 of cylindrical shape with convex top 6 and bottom 7. lit is do" signed to maintain this tank nearly but not quite full of condensate, a space being left above the liquid -for the fixed gas. a considerable proportion of which is ordinarily (loveloped, particularly in distillalion under that the space about the coo no 191.

At 8 we have shown a connection to provide for the escape or withdrawal of tlie fixed gases, which may be conwhich uected to a gasometer or to means the pressure of the may be re; pressure. may be either above u'ios plieric depending upon iia: method of operation.

Provision is made sate by circulating coolers outside the tank proper. in. tire preferred form of the iuveution shown there are eight oi these coolers 1O erg-rally spaced about the drum or tank, eael'i. com" cylindrical body 12 in common. the task towards its u operend i.) tion 11 and towards its lower elbow-connection con'iprisiug the pipe 13 and the vertical fol.

The other lie-ruler may be com nected either to waste or to a receptacle for for cooling the coodew "the liquid which has been. used for cooling purposes file headers are provided respectively with "the connections 1?, it and connected by the cooling tubes l'il -tliroueo which the cooling liquid or flui flows from one header to the other. lit w ll be observed in tubes is in coiru'uiuiication with the tamaauz'l toe contents of the latter are free to flow there tlu'ougl'l. in order toiuduce tile (flrfilililtifil'l of the liquid through the coolers the vapors coming from the still are iutrmlueed at 20 in each clliow-mumectiou between pipes 13, 14 and in the direction of ice latter pipe. The injection oi the vapors and such fixed gases as they contain in this manner and under the pressure at which they come from the still causes an injector action in the pipe 1} which has the-effect of drawing the con oensate from the cooler so that there is a it through a series of continuous and rapid circulation of liquid lit hill

the cooler, and the pipes 13, 14. The pipe 14 in each instance is rovided with or connected to a nozzle 21 aving a reduced end and over said reduced end is arranged a series of frustro-conical deflectors 22,23, 24,

.which are secured in spaccdrelation in any suitable manner so as to leave between them passages for the liquid in the tank. The vapor and liquid issuing from the nozzle? 21 therefore draws in the liquid between the deflectors and mixes it with the vapors and liquid coming throu h the nozzle 21. Provision may he made $01 drawing off the condensate at any desired point but we prefer to provide for this purpose .a draw-0E 26 at or near the level at which it is proposed to maintain the condensate. lltis also desirable to provide draw-off openings at oints where any heavier matters contained in the condensate are apt to collect, and for this purpose we have shown a draw-oil 27 at the bottom of the tank and draw-offs 28 near the bottoms of the respective coolers.

From the foregoing the operation of our improved condenser will. readily be understood. The injection of the vapors under high pressure at 20 causes a rapid circulation of the liquid from the tank through the respective coolers, reducing the temperature of the condensate so that when it is mixed with the vapor entering through the pipe'2t) it is in suitable condition to rapidly condense the vapor. The mixture of vapor and condensate rising throu h the pipe is and nozzle 21 and issuing t rough the latter and through the conical deflectors causes a corresponding series of eddy currents in the tank which bring additional quantities of fresh condensate directly in contact with the vapors issuing through nozzle ll, further cooling the vapors so that they are thoroughly condensed and only the non-condensahle fixed gases escape through the surface of the condensate and into the space about the same. The pressure above the condensate may be maintained at any point desired, whether alcove or helow atmospheric, by suitably controlling; the exhaust of fired gases from the tank.

. We claim:

1. ln an apparatus for condensing vapors, a closed tank adapted to contain the condensate thereof, a cooler, a pair ot' connections between the cooler and the tank to provide a closed circulation from the tank through the cooler and hack to the tank, means for injecting the vapors below the normal liquid level in said tank, and means for withdrawing condensate from the tank.

4. In an apparatus for condensing vapors, a closed tank adapted to contain the con- (lensutc thereof, a cooler, 21 pair of connections between the. cooler and tlrc tank to provide a closed circulation from the tank through the cooler and back to the tank, means for injecting the vapors in concurrent flow with the condensate from the cooler into the tank, and means for withdrawing condensate from the tank.
